Title: Bayard-alpert vacuum gauge with neutralization of x-ray effect
Inventor: KENDALL BRUCE R F
IPC: G01L21/34
Filed: 1998-05-08
Abstract: A Bayard-Alpert gas pressure measuring gauge with x-ray effect neutralization comprising collector and shield electrodes that comprise the same substantially inert electrically conductive substances. Said inert substance may be gold or another substance from the group consisting of platinum and rhodium, and mixtures thereof, and alloys comprising gold, platinum or rhodium; or said substance may be selected from the group consisting of the oxides of indium, chromium, vanadium and tin, mixtures thereof, and alloys comprising one of these. An electrical potential is applied to the shield that is more negative than the potential applied to the collector, said potential on the shield being in the range from about zero volts to about -50 volts when the collector is operated at a positive potential. Said negative potential with respect to the collector enhances the reverse x-ray effect for cancellation of the forward x-ray effect in the gauge. The gauge may also comprise a modified collector geometry to further enhance the reverse x-ray effect to achieve neutralization of the total x-ray effect. A method for neutralization of the x-ray effect by modulating the shield potential is also disclosed.

A method consistent with the present invention uses a per-frame reporting mechanism based on tracking frame erasure indicator bits to achieve quality cellular service and efficient system operation.
Patent CA-2293161-A1 (CA)
Title: Monitoring data of a selected call in a wireless telecommunication system
Inventor: DO TUAN ANH
IPC: H04W24/00
Filed: 1999-12-30
Abstract: A method and apparatus for obtaining call record information in a mobile telecommunication switching system. The information is obtained, not only from the base station serving a call at the time that of the call record information is requested, but also for obtaining such information from prior base stations serving the call and subsequent base stations serving the call. Whenever a call is handed off, the identity of the call record and the handing off base station, as well as the identity of the handing off base station and the mobile switching center (MSC), serving the call in the previous base station are recorded in the handed to base station. When a request for call record information is received, the base station serving the call transmits such call record information, and also transmits a request to the immediately prior base station to transmit its call record information from the identified call record. The predecessor then requests a similar action from its predecessor, if any. The initial base station for serving the call is initialized to record that it has no predecessors. Advantageously, this arrangement allows call record infor-mation from all predecessor base stations to be obtained, and transmitted an MSC for subsequent processing in an operation support system.

Title: Disposable pull-on pant
Inventor: CARLIN EDWARD PAUL
IPC: A61F13/496
Filed: 1996-03-29
Abstract: Pull-on garments provided with a continuous belt (38) is the front region (26) sad the back region (28) to distribute the forces generated during use is order to better fit the pull-on garment on the wearer. In a preferred embodiment, the pull-on garment comprises a chassis layer (40) comprising a continuous sheet that defines a front region, a back region, and a crotch region (30), first belt layer (42) joined to the chassis layer in the front region; a second belt layer (44) joined to the chassis layer in the back region; elastic laminate panel members (46, 48, 50, a.o.) positioned between the belt layers and the chassis layers which laminate is mechanically stretched to form elastically extensible strech laminates in both the front region and the back region in the side panels (64), and seams (32) joining the front region to the back region so as to form the leg openings (34) and waist openings (36). The continuous chassis layer and belt layers thus form the continuous belt of the pull-on garment. Because the belt layers extend continuously laterally across the waist region and do not cover the entire crotch region, and because the chassis layer is thus exposed in the crotch region, the pull-on garment has a unique aesthetic feature which consumers perceive as providing a cloth-like feel in the waist but containment characteristics in the crotch.

Title: Reel for dispensing and collecting electrified wire
Inventor: LEVINE KRISTEN M
IPC: A01M29/24
Filed: 2000-05-17
Abstract: An apparatus for protecting the gate of an animal enclosure with an electrified wire that also extends along fencing includes a reel that dispenses and collects the wire to minimize the possibility of shock during gate opening and closing procedures. A hollow reel housing is mounted to a first fence post to which the gate is hingedly attached. A truncate wire connected to a source of electrical power such as an electrified fence wire extends into the hollow reel housing through a first opening and is connected to a nonrotating electrical contact. An annular rotating electrical contact is in electrical communication with a proximal end of wire coiled about the reel and is mounted on the reel so that the wire remains in electrical communication with the source of power when the reel is rotating in a wire-dispensing direction or in a wire-collecting direction. The wire, when uncoiled, extends through a second opening formed in the hollow reel housing. The distal free end of the wire is connected to a handle latch member that engages a handle catch member mounted on a second fence post adjacent the free end of the gate when the uncoiled wire is extended across the gate. The handle latch member includes an insulated handle which is grasped during wire dispensing and collecting. The reel is spring-loaded and loads during dispensing and unloads during collecting.      An indicator light is illuminated when power is supplied to the apparatus.

Title: Refuse incinerating oven
Inventor: WU KUN-CHENG
IPC: F23J15/04
Filed: 2000-05-24
Abstract: A refuse incinerating oven includes a refuse loading car, and a furnace body with lower and upper combustion chambers. The car is conveyed through the furnace body such that refuse loaded on the car can be ignited in the lower combustion chamber. The combustion exhaust generated in the lower combustion chamber flows into and is heated in the upper combustion chamber. A spraying tank is communicated with the upper combustion chamber for receiving the combustion exhaust. Water mist is sprayed to the combustion exhaust in the spraying tank so as to generate aerated water. The aerated water and the combustion exhaust flowing from the spraying tank are cooled as they flow into a reservoir. The aerated water is pumped from the reservoir to an upper end of a waterfall tank so as to generate a downwardly cascading water stream inside the waterfall tank. An exhaust port unit is connected to the upper end of the waterfall tank for sucking and releasing the combustion exhaust.

Title: Process for making polyetherester resins with high aromatic ester content
Inventor: ARMSTEAD DIANDRE
IPC: C08G63/183
Filed: 1999-02-09
Abstract: A process for making polyetherester resins is disclosed, wherein a glycol ester of an aromatic diacid such as terephthalic acid is reacted with a polyether and a source of a dicarboxylic acid such as maleic anhydride to produce a polyetherester resin, wherein the aromatic diester content may be conveniently adjusted as desired. The process permits the preparation of unsaturated polyetherester resins with relatively high levels of terephthalate repeating units while avoiding the difficulties associated with the direct use of terephthalic acid in previously known procedures. Such unsaturated polyetheresters are useful for making thermoset resins with excellent mechanical and physical properties. New glycol esters based on 2-methyl-1,3-propanediol, compositions of such glycol esters and 2-methyl-1,3-propanediol, and polyester resins and thermosets made from the glycol esters, are also disclosed.
